The Invertec® V311-T AC/DC User interface con- sists of the following (Refer to Figure B.3):

1.DYNAMIC LCD DISPLAY

2.STATUS LED LIGHTS

a.VRD On (Voltage Reduction Device) Status Light- Voltage reduction device can be enabled from the set-up menu so that an output voltage limit can be set that reduces the output open circuit voltage to a safer level when not welding. If enabled when the machine is sitting idle in stick mode the Green VRD on light will illuminate to indicate the voltage is reduced below the set limit. If the VRD device is not enabled (factory default) from the set up menu or while weld- ing the red VRD off light will illuminate to show that output voltage is present above the limit.

Note: The green VRD on light will illuminate in TIG mode until the output is triggered even when VRD is disabled. Also note that enabling VRD to reduce the output voltage can make striking a stick elec- trode more difficult.

b. General Alarm – Yellow LED which is lit when faults exist with the power source or optional cooler, such as over temperature, coolant blockage, etc.

c. Output On (No VRD) – This status light will illu- minate red whenever the output in electrically hot and the voltage level is above the VRD threshold value.
